I have an outdoor AP (Engenius EOC2610) which I have used for almost a year. Recently I ran into a problem when using a long (15 meter) Ethernet cable to link a fixed Internet connection to the AP. The link looks like this: Internet RJ-45 port to 1 meter Ethernet cable to PoE injector to 15 meter Ethernet cable to AP RJ-45 port. Although the AP's power LED is lit, other LEDs show some problems with LAN and WLAN connections. If I replace the 15m cable with a 1m cable, the AP works just fine. I have used a tester to verify that all cables are good. What could be wrong, and what should I try to overcome this problem?
